the problem for me is that people who look like me are often scapegoated more so than other folks, and as a scientist who knows the facts about drugs, that's very disturbing. >> host: i would think as a black person it would be very disturbing. >> guest: that's exactly what i mean. >> host: let's stop for a second and try to understand something that is race related in this regard, which you say is just an outrage, which is the fact that when you look at something like the 1980s and the crack cocaine use, you say, people identify this as a black committee problem but, in fact, more whites used crack and blacks. and similarly more blacks went to jail, arrested for crack use and waste and even though more whites were using the drug. how do you explain that?
